Description
Technical field
The utility model relates to a kind of hinge, particularly a kind of elastic-friction rotational-positioning hinge that makes object keep several angle or certain position.
Background technique
Many apparatus, electrical equipment, communicating terminal etc. all have both to have been needed to rotate, need again the frame connecting structure spare fixed--hinge, much do not have automatic locking positioning device, mainly there is the problem of following aspect in existing band lock-bit function hinge:
1, conventional hinge is generally clamped rotatingshaft sheet and the clamping bolt that a slice is connected with moving support by two stationary axle sheets that are connected with fixed rack and is formed, fix with the method for bolton then, damage the screw thread (be commonly called as and lose tooth) of bolt during this hinge uses easily; And locating effect is poor, behind the clamping bolt, still occurs loosening easily repeatedly.
2, the self-latching hinge of common notebook use, when after opening the computer monitor several angle, adjusting display device, spring clip in the hinge means is opened under pressure, can make display device keep several angle, though this hinge has its advantage, but its complex structure make also complexity, and torque value is less.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, not fragile, a kind of elastic-friction rotational-positioning hinge that the lock-bit performance is good, easy for installation is provided.
The utility model is finished with following mode.
Elastic-friction rotational-positioning hinge is installed on the backing-up screw successively by cushion block, elastic element, hinge plate A, elastic element, hinge plate B, elastic element and cushion block, and is tightened through nut; Hinge plate A is the plate of a rectangular bending, and wherein the side plate center position is porose, and there is spacing pulling the outer, and another side plate has mounting hole; Hinge plate B is the plate of a rectangular bending, and wherein the side plate center position is porose, and there is limited impression the outer, and another side plate has mounting hole; Limiting board is installed in the limited impression.
Can regulate the rotation elasticity of hinge plate B by the degree that screws of adjusting nut, binding nut is contained in the terminal of backing-up screw and near nut.
Hinge plate A and hinge plate B bending part are pressed with stiffening rib.
Hinge sleeve be set with or spinning on two cushion blocks.
Elastic element is a belleville spring.
Elastic element is a sheet rubber.
Elastic element is a plastic sheet.
The utility model is simple in structure, the lock-bit performance is good and easy for installation, not fragile, the rotation elasticity that can regulate hinge plate by the degree that screws or the elastic element of adjusting nut, also can regulate the angle of hinge plate B 5 around the rotation of backing-up screw axis by the aperture that changes the hinge plate B limited impression, this hinge can be widely used in industries such as household electrical appliances, furniture, jewellery case and portable communication terminal.
Description of drawings

Fig. 2 is the cross-sectional schematic of Fig. 1;
The structural representation of Fig. 3 hinge plate A;
The structural representation of Fig. 4 hinge plate B.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Present embodiment elastic element 4 adopts belleville springs, and every group is combined by two belleville springs.Elastic-friction rotational-positioning hinge is mainly constituted by hinge plate A 3 and hinge plate B 5, backing-up screw 1, two cushion blocks 2, three groups of belleville springs, nut 6, binding nut 7 and two hinge sleeves 8.Cushion block 2, belleville spring, hinge plate A 3 (by hole 12), belleville spring, hinge plate B 5 (by hole 13), belleville spring and cushion block 2 are installed on the backing-up screw 1 successively, and are tightened through nut 6; Hinge plate A 3 and hinge plate B 5 spaces are installed between three groups of belleville springs, because screwing of nut 6, two cushion blocks 2 push to belleville spring mutually, make belleville spring distortion and closely contact with hinge plate A 3 and hinge plate B 5, and mutual extrusion, if connect object and fixing with hinge plate A 3 by mounting hole 14 usefulness screws this moment, external force is pulled hinge plate B 5 and is connected and mounting article by mounting hole 14 usefulness screws, because the compressibility of belleville spring, hinge plate B 5 is rotated around the backing-up screw axis, but hinge plate B 5 lateral plates that have hinge plate A 3 lateral plates in hole 12 and have a hole 13 can produce strong elastic-friction with belleville spring, the frictional force that is produced can overcome the self gravitation that connects hinge plate B 5 objects, therefore, shed external force, connect hinge plate B 5 objects and still can be positioned on fixed position, reach hinge lock-bit effect.
Hinge plate A 3 of the present utility model is plates of a rectangular bending, and wherein the side plate center position is porose 12, and there is limiting board 9 outer, and another side plate has mounting hole 14; Hinge plate B 5 is plates of a rectangular bending, and wherein the side plate center position is porose 13, and there is limited impression 10 outer, and another side plate has mounting hole 14; Limiting board 9 is installed in the limited impression 10, can limit the angle of swing of hinge plate B 5, can regulate the angle of hinge plate B 5 around the rotation of backing-up screw axis by the aperture that changes hinge plate B 5 limited impressions 10.
The utility model can be regulated the rotation elasticity of hinge plate B 5 by the degree that screws of adjusting nut 6, and binding nut 7 can prevent that near gland nut 6 nut 6 is owing to the frequent use of elastic-friction rotational-positioning hinge is become flexible.
Hinge plate A 3 of the present utility model and hinge plate B 5 bending parts are pressed with stiffening rib 11, can strengthen the intensity of fixed plate A 3, B5, and the size of also visual connection object or weight are selected the thickness of the material of manufacturing usefulness.
Two hinge sleeves 8 of the present utility model be set with or spinning on two cushion blocks 2, make the utility model external form more attractive in appearance, material can be plastics or metal.
